■ Histogram
• A histogram is a graph that displays
brightness along the horizontal axis (black
to white) and the number of pixels at each
brightness level on the vertical axis.
• It allows the camera user to easily check
the way a picture is being exposed.
• When the values are concentrated to the
left
A, the picture is under exposed.
Pictures that are mostly black, such as
night scenery, forms this type of
histogram.
• When the values in the histogram are
distributed evenly
B, the exposure is
adequate and the brightness is well-
balanced.
• When the values are concentrated to the
right
C, the picture is over exposed.
Pictures that are mostly white, forms this
type of histogram.
Example of histogram
A Under Exposed
B Properly Exposed
C Over Exposed
